Griffin PowerDuo Reserve Lithium-Ion (Li-Ion) 500mAh Black power bank

PowerDuo Reserve AC and car charger plus rechargeable backup battery Griffin’s best-selling AC and 12 volt DC chargers together in one package. And, as if that weren’t enough, you get a pocket-sized backup battery to take with you.

PowerBlock is our near-universal AC charger/adapter for USB-rechargeable devices, including iPod, iPhone, and other phones and MP3 players. And PowerJolt does similar duty from the cigarette lighter or 12 volt accessory socket of your car.

PowerBlock delivers safe power levels from almost any 100 to 240 volt AC wall socket. Plug PowerJolt into your cigarette lighter or 12 volt power outlet to charge your player in your car while you use it. PowerBlock and PowerJolt both work with iPhone, iPod, mobile phones, MP3 players, and almost any other device that charges by a standard USB connection.

It’s hard to imagine a situation the PowerBlock/PowerJolt power duo can’t handle, but this Reserve package prepares you even for that. Take the detachable battery pack with you (it’s small enough to fit in your jeans watch pocket). The Reserve battery snaps into the Dock Connector of your iPod or iPhone, adding hours of additional use. No more worrying about battery life; and no need to lug your charger along with you when you leave the car.

PowerDuo Reserve is the most USB charge you can pack into the smallest footprint.
